Abstract

The iodate oxidation of sulfite and ferrocyanide when carried out in a continuous flow stirred tank reactor exhibits large-amplitude oscillations in pH accompanied by an almost constant concentration of iodide. A description of the reaction in terms of component processes and associated empirical rate laws is used to model the dynamical behavior. Limitations and potential refinements of the empirical rate law model are discussed. A detailed mechanism consistent with the component process description is presented.
